3D discrete dislocation dynamics applied to a motion of low-angle tilt boundaries
Original language description
This paper presents a 3D discrete dislocation dynamics (DDD) model describing dislocation processes in crystals subjected to loadings at high temperatures. Smooth dislocations are approximated by short straight segments. Every segment is acted upon by aPeach-Koehler force obtained by summing up forces from all dislocation segments and a force due to the applied stress. The model addresses interactions between individual dislocations and rigid precipitates. The model is applied to a migration of low angle tilt boundaries (LATBs) characterized by different initial dislocation density and constrained by precipitates of different sizes. The calculations showed that, for applied shear stresses _xz lower than a certain threshold _crit:(h), the LATB is inhibited by the precipitate field. For _xz above _crit:(h), the LATB passes through the precipitate field. Some combinations of _xz and h lead to a decomposition of the LATB. The LATBs thus may evolve in three distinct modes depending on the
